This work is researching the potential of the revitalization of Zagreb industrial heritage that is, unfortunately, mostly in bad condition, not valorized enough or preserved as identity markers of the city, areas most often marked as brownfields, neglected spaces of high potential whose revitalization could improve the quality of life of the citizens and preservation of the identity markers of the city. The main focus of this work is the former Nada Dimić factory area, as a recent example of repurposing of the former factory area into an area of a mixed, mostly residential purpose, analyzing whether those residential buildings revitalized the area (of the former factory as well as the broader area around the neighborhood, or even the city center) and, in what way would the introduction of the public, social and cultural contents bring to improvement of the quality of life and the preservance of identity markers of the city of Zagreb. The analysis of the publically available cadastral data of the city of Zagreb, as well as the other relevant documentation) reveals the state before and after the construction of the residential-commercial complex 'Park kneževa', as well as the quantity and diversity of the content provided by the Medika, Pogon Jedinstvo or Lauba which were taken as examples of successful revitalization of brownfields. The current state of the former factory 'NADA DIMIĆ' was analyzed using methodology based on Gehl's criteria of public space quality. The work is offering several repurposing options, a form of ownership over this space, emphasizing what could be the most important in revitalization of this area, and by that improve the quality of the urban life and preserve the identity markers - involving all the stakeholders, formostly the citizens, in the process of conceptualization of the contents, so that diverse contents could be realized and the space made more suitable to different groups of people, emphasizing the need for urgent realization of public contents that would make this space a bearer of the city identity and it's industrial heritage.
